INVENTOR WITNESSES ATTORNEY UNITED STATES CHARLES E. MARTIN, OFIZIOUISVILLE; KENTUCKY.

HAIR-DRIER.

Application filed June 20, 1919.

To all whom it may concern: Be it known that I, CHARLES E. MARTIN, a citizen of the United States, residing at Louisville, in the county of Jefferson and i upper end having an interior partition chamber.

dividingthe easing into an upper and relatively shallow chamber and a lower larger An elbow or duct connects the two chambers and is designed to house airdriving means such as an electric fan. The lower compartment houses air heating means. Extending from the upper compartment there is a plurality of air directing means, which may be in the form of funnels suitably arranged as to height and disposition to accommodate several people at the same time.

The invention will be best understood from a consideration of the following de tailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the-drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings Figure 1 is a perspective view of the hair drying apparatus.

' Fig. 2 is a diametric vertical section thereof.

Fig. 3 is a section on the line 3--3 of Fig. 2.

Fig. 4 is a section on the line 44 of Fi 2.

Ileferring to the drawings there is shown a drum 1 which may be of cylindrical shape, as shown in the drawings, or of any other appropriate shape. The drum is shown as mounted upon legs 2 thereby elevating 1t a short distance but it is to be understood that the drum may be supported in other Specification of Letters Patent.

ways than upon legs. The interior of the drum is divided into two compartments 3, 4 respectively, by a partition 5 which may be considered as extending horizontally across the interior of the drum. The partition 5 is located nearer to the top of the drum than to the bottom thereof, whereby the chamber 3 is considerably smaller in capacity than the chamber 4, considering the drum as of even diameter throughout. It is to be understood that the invention is not confined to any particular drum or body member 1, or any particular position of the partition 5.

In the bottom of the drum there is located a section 6 which may be made of woven wire fabric, the section 6 providing communication between the interior of the bottom portion of the chamber 4 and the atmosphere. Lodged above the wire fabric section 6 is a heater 7 which may be of any of the familiarforms of gas heaters, such as a hot plate, and this heater is fed with fuel by a pipe 8 extending to some exterior source of gas.

Within the chamber 4 is an elbow 9 opening at one end 10 through the partition 5, and at the other end opening into the chamher 4 and carrying and electric fan 11 or any other suitable type of air propelling device driven by a motor 11 fed with current through a conductor 12 including a suitable form of electric switch 13, the conductor being assumed to be connected to -a source of current such as a service line. By placing the motor, 11 outside of the chamber 4 there is no danger of overheating and so injuring the motor or conductors. Adjacent to the heater 7 the drum 1 is provided with a door 14 and in position to give access to the electric fan 11 thereis another door 15 in the walls of the drum 1. In order to strengthen the elbow .9 suitable braces 16 are provided. At any convenient point in the drum 1, preferably at a high point in the chamber 4 there is an outlet flue 17 for gases of combustion.

The walls of the chamber 3 are provided with numerous openings-18 each covered by a guide 19 for a slide or damper 20 and alining with each hole 18 is a funnel 21 with the large end outward. The funnels 21 may be all arranged at the same height, say about four feet from the floor, although such particular height is not obligatory. The hei ht mentioned, however, will accommodate grown people seated upon chairs or stools and children standing upright, the tunnels 21 being then about on a level with the heads of the persons.

When it is desired to use the drier, the heater 7 is lighted, thus heating the air in the chamber 4. The heat may be regulated by a valve 22 at the heater 7 and accessible through the door ll or in any other suitable manner. When the air within the drum 1 is sufficiently heated the motor 11 is started and the heated air from the chamber 4 is forced through the elbow 9 upwardly into the chamber 3 at about the mid-point thereof. The heated air distributes through the chamber 3 and out through the openings 18 or such of these openings as are not closed or partially closed by the dampers 20. The heated air is projected in expanding streams through and from the funnels 21 and the hair of the persons being treated is subjected to the hot air, thereby quickly drying the hair and at the same time thoroughly aerating it. The amount and force of the air streams may be readily regulated at each funnel 21 by the slide 20. The degree of heat imparted to the air in the chamber at may be readily regulated by the valve 22. The force of the air streams issuing from the funnels 21 may be further regulated by the control of the electric fan 11. The flue 17 permits the escape of the gases of combustion from the heater 7 when the fan 11 is not in operation.

It will be understood that where other sources of heat than gas are available other types of heaters than the gas heater 7 may be used. Where steam heat is available,

steam coils may be installed inside of the drum 4: and in some instances it may be economical to employ electric heaters. These, however, are matters of convenience and environment.

The hair drier is particularly valuable in places such as club houses, bathing resorts, swimming pools and the like, where numerous persons desire the hair to be dried, and the multiple hair drier of the invention makes it feasible to so treat a number of persons simultaneously with the instrumentalities employed, with such instrumenta1ities of small compass.

What is claimed is 1. A multiple hair drier comprising a drum internally divided into upper and lower chambers with communication between them, the upper chamber having a series of air directing devices extending therefrom, the lower chamber having heating means therein and the sole means of communication between the chambers having air propelling means, whereby air heated in the lower chamber may be driven into the upper chamber and distributed, through the various air directing devices.

2.
